FIXED PARTITIONING
In a fixed partitioning, the operating system inhabiting some fixed portion of main memory is available for use of multiple processes
-Using fixed partitioning we are able to allocate the memory
-Here we can divide the memory into some fixed partitions
-Each partition may possibly not be of the size
-For every partition we have an input queue
-If we have the process enters
Analyze the process as well as choose the smallest partition in the memory for that to be properly fitted. That is the smallest portion in the memory which can fit that process in it properly.
Two difficulties:
- The programmer may possibly have to rewrite a program in order to fit into even the largest available partition. Overlaying may perhaps be used.
- Internal fragmentation usually a result there's memory that is unused within every partition.
